2014 among the hottest years on record.

This is an update to my previous post on this topic, which was based largely on January-November data. The full-year data is rolling out and no matter who is measuring, 2014 was a hot year for the Earth.

UAH came out first, showing that 2014 was the third hottest year in the satellite record for temperatures 1 km above the planet's surface.

Now NOAA and GISS surface temperatures have joined the chorus. For both, 2014 was the hottest year on record, despite ENSO-neutral conditions in 2014. We're in a position now where our ENSO-neutral years are hotter than the El Niño years of the past 20+ years.

While my previous post found that 2014 was the third hottest year in the UAH record and hottest year in the NOAA record, it was "only" the second hottest year for GISS based on January-November temperatures. An exceptionally warm December (anomaly of 0.72ºC, the second hottest in the GISS record) was the difference. For the entire year, the GISS temperature map looks like this:

Note just about the only area in the Northern Hemisphere that was below-average in 2014? Yep, the good ol' eastern USA, partially explaining all those "the US is cold so there's no global warming" memes floating around the Internet.

While rounding may help a bit, the prediction based on the overall trend was quite accurate. 2014 was slightly above the expected temperature for UAH while NOAA and GISS were right at the expected temperature based on their respective trends. There was nothing anomalous about 2014 setting a new surface temperature record—it was right on the trend.

Last, a very hot year by itself says little about global warming. However, the fact that 2014 was so warm without an El Niño adds to the existing evidence that the pause does not exist.

I have a question A denier quoted a paper "The estimated average Greenland snow temperature over the past 4000 years was −30.7°C with a standard deviation of 1.0°C and exhibited a long‐term decrease of roughly 1.5°C, which is consistent with earlier studies. The current decadal average surface temperature (2001–2010) at the GISP2 site is −29.9°C. The record indicates that warmer temperatures were the norm in the earlier part of the past 4000 years, including century‐long intervals nearly 1°C warmer than the present decade (2001– 2010). Therefore, we conclude that the current decadal mean temperature in Greenland has not exceeded the envelope of natural variability over the past 4000 years...""http://www.leif.org/EOS/2011GL049444.pdf

I think the denier got his information from here "New study shows temperature in Greenland significantly warmer than present several times in the last 4000 years" http://wattsupwiththat.com/2011/11/10/new-study-shows-temperature-in-greenland-significantly-warmer-than-present-several-times-in-the-last-4000-years/

I would like to thank you for the efforts you have made in writing this article. I am hoping the same best work from you in the future as well. In fact your creative writing abilities has inspired me to start my own BlogEngine blog now. Really the blogging is spreading its wings rapidly. Your write up is a fine example of it.top cyber monday deals 2014

An anonymous commentator on my post about Tom Luongo raised the issue of John Casey and his views on climate change. This is a valid challenge, since Luongo apparently got much of his misinformation from Casey.

An old friend posted an "article" by Tom Luongo, a former chemist (B.S. from the University of Florida) who now writes the Resolute Wealth Newsletter, on Facebook. Unfortunately, that article is chock full of lies about climate science. Since Facebook comments aren't the best forum for debunking Gish Gallops, I'm taking the liberty of debunking them here.

[Update: Since Luongo got most of his claims from John Casey, I've written something about his brand of science here.]

Recently, a right-wing cousin of mine shared a meme claiming that
global temperatures were unchanged between 1996 and 2016, specifically
that global temperatures were 14.83ºC (58.7ºF) in both 1996 and 2016.

I call BS and here's why.

First
and most obviously, 2016 isn't even half over. Stating that the mean
temperature in 2016 was 14.83ºC (58.7ºF) is a bit premature.

Second,
whoever came up with that meme has extreme difficulty with basic
statistical terms. Here's a hint: "Average mean temperature" is
nonsense. As used in everyday speech, it's essentially the same as
saying "average average temperature" or "mean mean temperature." Now,
for those who understand statistics, I know that the mean is technically
a specific method for calculating the average but in general usage,
mean and average are interchangeable—and whoever came up with that meme
was abjectly ignorant of that fact.
